A Dictionary of Music and Musicians/Baritone
BARITONE, the name usually applied to the smaller bass saxhorn in B♭ or C. It stands in the same key as the euphonium, but the bore being on a considerably less scale, and the mouthpiece smaller, it gives higher notes and a less volume of tone. It is almost exclusively used in reed and brass bands, to the latter of which it is able to furnish a certain variety of quality.
